	* debian/changelog: Add entry for new Debian upload.
        * linux/dev/drivers/scsi/seagate.c (WRITE_CONTROL, WRITE_DATA):
        Added from linux 2.2.15.
        (__asm__ constructs): Replace with equivalent C code from linux 2.2.15
        to support gcc-2.95.
        * linux/src/drivers/scsi/in2000.h: Update asm code to linux 2.2.15.
	* linux/src/drivers/scsi/ppa.c: Replace asm code with equivalent
	C code from linux 2.2.15.

2000-02-06  Stefan Weil <stefan.weil@de.heidelberg.com>

	* device/subrs.c: Fixed compiler warning.
	* ddb/db_output.c, kern/bootstrap.c, kern/debug.c, kern/printf.c:
	Replaced varargs.h by stdarg.h. Fixed prototypes (const char *fmt).
	* ddb/db_output.h: Use prototype for db_printf.
	* i386/Files: removed varargs.h.
	* i386/i386/pit.h: Fixed compiler warning.
	* i386/i386at/model_dep.c: Tried to fix compiler warning.
	* i386/include/mach/sa/sys/varargs.h: Removed.
	* i386/linux/Makefile.in: Removed delay.S, added delay.c.
	* linux/dev/include/asm-i386/segment.h: Support gcc-2.95.
	* linux/dev/include/asm-i386/string.h,
	linux/src/include/asm-i386/string.h: Update from linux-2.2.14.
	* linux/dev/lib/vsprintf.c: Fixed compiler warning.
	* linux/src/include/asm-i386/delay.h: Update from linux-2.2.14.
	* linux/src/arch/i386/lib/delay.c: Copy from linux-2.2.14.
	* linux/src/include/asm-i386/string.h: Update from linux-2.2.14.
